Portfolio overview

YANGTZE MEMORY TECHNOLOGIES CO., LTD. has been granted 1,087 US utility patents between 2018 and 2025, placing YANGTZE MEMORY TECHNOLOGIES CO., LTD. at rank #414 across all assignees tracked by PlainPatent. This portfolio spans 37 distinct Cooperative Patent Classification (CPC) subclasses, averaging 18.3 claims per patent with primary concentration in H10B (ELECTRONIC MEMORY DEVICES). As a Foreign Corporation, YANGTZE MEMORY TECHNOLOGIES CO., LTD. is one of the more focused assignees in the PatentsView dataset. The composite Innovation Score of 71.1/100 blends portfolio volume, filing velocity, technology breadth, and claim depth into a single comparable measure drawn directly from USPTO PatentsView records.

Filing cadence tells the strategic story. Between 2020 and 2025 the company received 1,076 grants, compared with 11 in the 2015–2019 window — a +9682% shift in five-year velocity. An acceleration of this magnitude signals aggressive R&D investment and expanding technical ambition. The Foreign Corporation classification further shapes interpretation, since corporate, government, and individual filers pursue patents for materially different reasons.

Claim depth and technology breadth together indicate competitive posture. YANGTZE MEMORY TECHNOLOGIES CO., LTD.'s 18.3 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while a multi-domain presence across 37 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark YANGTZE MEMORY TECHNOLOGIES CO., LTD. against peers pursuing similar technology classes.
